This work concerns the reaction of the primary amine, 2-amino- 2- methyl-1-propanol with carbon disulfide to produce the amine salt of 1-methyl-(1-methylol)-ethyldithiocarbamic acid. This salt is then investigated to determine its physical properties and the possibility of use in copper analysis. A report is given on the reaction, and the purification and analysis of the reaction product. The colored reaction of the amine salt with copper and other metal ions is listed, and an analytical procedure for the determination of trace amounts of copper is given. Using the procedure described, accurate determinations of copper concentration to one ppm were obtained. The effect of pH on fading of the colored copper thiocarbamate was investigated and found to be negligible between the range of pH from 4 to 8. An attempt was made to determine if the colored compound formed by reaction of the amine salt with copper was a chelate. Potentiometric and precipitation titrations were carried out with inconclusive results.
